DigiCORA- and GRUAN-corrected data used in this study. As seen here the meridional width of the equatorial moist tongue varies considerably over this domain being broadest over the longitudes of the Maritime Continent. Straddling this moisture maximum, the three sites span a broad range of moisture conditions ranging from a moisture-rich environment at Manus to more arid conditions at Nauru, which sits on the eastern edge of the west Pacific warm pool. The time–longitude plot of TPW for this period

al. (2013) . One of the primary goals of ACDC was to thoroughly investigate the moisture structure of the pre-MJO environment in order to assess the likelihood that changes in the lower-tropospheric moisture structure could act as a trigger mechanism for MJO onset. One tool for investigating changes in moisture structure is Bragg scattering layer (BSL) analysis. BSL analysis is a procedure to extract moisture-structure information from S-band radar by analyzing plan position indicator (PPI

associated wind fields within the MJO. It is hypothesized that a variant of the WISHE mechanism helps drive the organization and evolution of tropical MCSs in a manner that is independent of geographic location (see Solodoch et al. 2011 ). That is, wind-driven turbulent fluxes of heat and water vapor from the ocean surface supply moisture to support convection. This convection in turn produces precipitation-laden storm outflows that increase local winds, which then provide additional water vapor in a

been suggested to be important to the initiation of the MJO ( Johnson et al. 1999 ; Kemball-Cook and Weare 2001 ), and in inducing low-level large-scale moisture convergence (by providing low-level latent heating when they precipitate), which helps convective development of the MJO ( Zhang and Hagos 2009 ; Yoneyama et al. 2013 ). The main objectives of this paper are to evaluate the ability of the cloud and precipitation radars deployed at Addu Atoll to document the full spectrum of cloud
